Understanding the Conversion from Kilograms to Pounds
What is a Kilogram?
The kilogram (kg) is the base unit of mass in the International System of Units (SI). It is defined by the Planck constant, making it a fundamental constant in physics. Historically, the kilogram was originally defined in relation to a physical platinum-iridium alloy cylinder stored in France, but since 2019, it has been defined using fundamental constants, ensuring greater precision and stability.
What is a Pound?
The pound (lb) is a unit of weight or mass used primarily in the United States and some other countries. It has origins in Roman and Anglo-Saxon systems and is considered a customary or imperial unit. The pound is widely used in everyday life, especially in measuring body weight, food portions, and postal weights.
